bin/54854: cvs pserver sig11 crash on 4.8-R

[Scott Mitchell]

Still seeing these crashes with a stock cvs 1.11.6 (ie. without any of the
FreeBSD extension).  The stack traces are very similar - it's interesting
to note that the crash seems to be triggered by bad cleanup from a SIGPIPE,
which I guess is related to the client-server connection closing down...

Anyway, it looks less likely that this is a FreeBSD problem, although I
still don't have any kind of solution other than using the binary from 4.6.
We're planning to swap out the RAM in this machine within the next couple
of weeks and run all the memory tests again, plus try all the versions of
cvs we've built, in case this changes anything.

Cheers,
